This invention discloses a method for intelligent greeting, explanation, and lead generation in architectural exhibition halls using a
digital human based on a
Finite State Machine (FSM), belonging to the field of 3D
virtual interaction and intelligent
customer acquisition technology. The invention utilizes a real-time user behavior acquisition unit to collect 3D
roaming behavior in milliseconds. The FSM
control unit incorporates five mutually exclusive states and a standardized transition matrix, driving the
digital human to intelligently switch between idle, greeting, precise explanation, lead generation guidance, and order placement states. The
digital human driving unit employs lightweight rendering and lip-synced
broadcasting for large architectural scenes. A scene-product linkage unit achieves native linkage between explanation and transaction. An intelligent guidance unit gently acquires high-intent leads. A data iteration unit optimizes
interactive effects in a
closed loop. This invention solves the industry pain points of traditional 3D exhibition halls, such as unattended operation, traffic loss, stiff interaction, disconnect between explanation and transaction, and inability to automatically acquire customers and generate leads. It achieves 365-day unattended intelligent operation, significantly improving user dwell time and business conversion rates. It is applicable to all scenarios, including 3D cloud exhibitions in the architectural industry chain, digital exhibition halls for building materials companies, industrial park investment promotion, and government and enterprise displays for urban renewal.
